How the Barcode Became An Integral Part of Our Lives | The Lightbulb Moment

[@techman2553]

It's too bad that the video didn't explain anything about how the barcode works or how they got a 1D barcode to be read in any direction. "Reconfigured the laser" doesn't explain anything. That it can be big or small doesn't explain anything. It's never mentioned that nation wide databases and standard codes had to be created so that the same product is uniquely identified anywhere and no two products in the same industry have the same code. The video boils down to just: Someone had an idea about a magic code, a brighter light was needed, microchips were needed, the shape changed, then it became really popular, then more shapes were created to store more info. There isn't much that the viewer learns that they couldn't have guessed.

I was a teenage grocery stockboy back in the 1960's and I can tell you, a grocer had to be a genius to keep up with inventory, you had to keep up with the replacement of inventory as items were sold and there were hundreds and hundreds of different items. Constantly, you either ordered too much or you were out of something else. While I wouldn't call it a nightmare, we found ways to get it done, today's people have no idea the mental powers it used to take to run a grocery store. The checkout girls were masters of memory and efficiency, too

I worked at a small convince store in the early 70s and I remember the weekly walk thru the store with the order book, for items Not on the NOW list, and then pricing each item before placing it on the shelf. The old manual cash register was still useable even with the power off; it had a hand crank to power it. These new electronic cash registers are useless if the lights are off; then they are only good as boat anchors. Ah the laser...an invention in search of an application: well, plenty have been found

My grandpa made the computer program that read the vertical barcode,, however he didn't work for IBM. He worked for the ARCO plutonium storage facility in Washington state.

I remember in the 60s that the grocery checker had to not only punch in the price but also the department in the store selling it. The largest department key on the keyboard was “Grocery.” The lazier checkers would often use that key for everything. Thus merchandise sold from the meat department would be credited to the grocery department. It was a real headache.

[@christinafidance340]

Those keys have a lot to do with tax as well since in some places, groceries aren’t taxed, but things like hot/prepared foods are or flowers or paper products, pet food, etc. I currently work in a small market in Pennsylvania and if the barcode isn’t working correctly on an item, I still need to use these buttons and while it has an inventory function, it’s also for tax purposes.

I had a neighbor who was a bit excentric. Prior to the bar code coming to our rural area all items had a priced affixed to each item. When an item changed price all existing inventory (of that item) had to be restamped with the higher price. My neighbor would dig toward the back of a shelf as there might be an item that didn't get repriced with a new pricing sticker. He said he was successful more often than not in getting a bit lower priced item, usually canned goods.

As a former cashier in the old days I took pride in accurately and quickly entering prices into my register. Barcodes still make errors at times, but significantly fewer than hand entered. Plus the fact that the receipt tells you what you bought, rather than just being a string of numbers. Fun fact: I remember when Mad Magazine came with its first bar coded volume. It was on the front cover with an arrow pointing to it and the caption “the world’s first computer-generated joke.” (If memory serves). Guess they thought it would be a fad.

Bar codes themselves make practically zero errors, since they have error-detection built in. (Read errors simply result in a failure to scan at all.) The real source of errors is the databases where the UPC codes are looked up in the POS software.

The white is the data, the black separates each number. I wrote software for a manufacture that had to print UPC numbers on their price tags in the early 90s.

Sorry, but no. In UPC both bars and spaces encode data. Same in most other symbologies. Very old fashioned "two of five" (non-interlaced) is the only one I can recall with variable width bars and fixed white spaces. Cool that you had to figure out how to get the data into a readable code! I knew a printshop that figured it out using multiple vertical rules with their phototypestter. It's part of how I transitioned into the bar code industry. In 2/5, I-2/5, Code39, narrow bars or spaces are read as "0" and wide bars or spaces are "1's".

1 D bar codes can certainly carry alpha as well as numeric characters. This video is great, but it seems very UPC oriented. The largest user of bar coding is the US military. That said, I think a bit of how UPC codes work would have been appropriate. The first part of each UPC symbol identifies a manufacturer, and the second half is a product number for that manufacturer's item. A worldwide organization (UCC) handles the assignment of manufacturer's ID numbers. I've been in the bar code industry for almost 50 years. I'd be glad to answer any questions!

I remember as a kid watching the checkers at the grocery store with the old style cash registers. Some of them could really fly over the keys, but even the fastest weren't as fast as the scanners. A lot of checkers didn't like the bar codes at first though. Being able to quickly enter prices was a skill people that were good at it were proud of. But it's a hard to argue with the advantages of the technology.

It did eventually start making my life easier letting me shop with more independence. 😎 I do remember working as a cashier without it being in use for several years though,even when many items had them printed on.

Saved my hands from making so many, braille labels, with a slate and stylus, on dymo tape. 😊

Big Box stores really were the death knell for department stores. They offer many of the same product categories, but in an even more convenient manner and the only two things they don't offer (large furniture and appliances) can be found in other stores, where it is more appropriate to go for a larger selection anyway. It used to be that big box stores just didn't have the same selections of things like clothing and kitchen or housewares and were still more focused on the grocery section, but that hasn't been the case since the late 90's. Nowadays, you're lucky if your big box store still has a quarter of the store devoted to grocery. Not that the selection has diminished, but that the size of modern big box stores has really ballooned over the years into truly gargantuan proportions. And, unfortunately, department stores just can't compete with that convenience or the broader selection of more specialized stores. Particularly when most developers go to the trouble of soliciting companies with offerings that fill in the gaps of their anchor stores to rent store fronts in their shopping centers for more comprehensive offerings. My local shopping center has a Target as the anchor store, a BJ's for bulk purchases, a Michaels for arts and crafts specialization, a Kohl's for clothing specialization, a Dick's Sporting Goods for sports specialization, a Rack Room Shoes for footwear specialization, and a Best Buy for electronics and appliance specialization. The developers really did try their best to make it a one-stop shopping location, despite the fact that the need for substantial parking means that you still need to drive around the shopping center unless you want to be very tired from walking.

The 13 numbers of the barcode actually has a meaning. The first 7 numbers are the territory's number, the other 6 are the product and the companies numbers

[@VoCodebcv]

Not exactly. The first part is always a manufacturer's ID, but the prefix in that number can identify a region. There are several coding schemes in retail bar codes. UPC in some places, EAN (European Article Numbering) is more region oriented. All use the same lines and spaces, or "symbology," but the way the numbers are encoded vary. There are a lot of schemes. Early on, all UPC codes that started with 0 were retail items. A first character 3 indicated medical goods. A lot of standards for the coding has changed over time.

[@VoCodebcv]

Think of a bar code as working like a car's license plate. It references a database. A cop can use your plate to get your name, address VIN, etc. A 1D bar code works the same way. A UPC code has a manufacturer's ID on the left side, and a product code assigned by the manufacturer in the right side. There is no price information. On scanning the numbers, the computer sytem looks up, say Frito Lay, and the code for 12oz bag of Doritos ranch chips, and returns the seller's price. 2D codes can do the same, but were developed to actually contain data in the cide itself. An early 2D code was called PDF code, for Portable Data File. QR codes are similar, but designed to hold website URL's for Quick Response to web references.

I don't know that having a lot of information in the barcode really matters, except maybe in very special cases. Generally it only needs to identify the item-the product, or in some cases the serial number as well. You don't need a lot of bits to nail that down. The other information can be retrieved online, more or less instantaneously. Of course, that wasn't the case in the early years of the UPC.

The problem with the quantity of numbers being finite is it limits the number of products. If it were smaller we would have run out a long time ago, but with the ever growing number of products available it is a problem we're facing today.

The barcode was invented by an Arisona farmer named Jackson Limpwood in 1826 when he had difficulty in tracking all his cattle. To do a cencus of his vast amount of animals cost a fortune in hiring men to count and record them. He first had the idea when he visited Amabooga wildlife reserve in Mamibia in Africa, and on seeing zebras thought the individual stripes the animals wore could be used as a count. Each of his animals were fitted with vertical stripes unique to each animal, when walked through a scanner at the time with a light bulb flashing at the US frequency of 60hz read the barcode so recording each animal. A bit crude at the time as the scanning equipment was housed in a container sized building, but it worked. Unlike the handheld scanners we have today.

The alternating field lines of a magnetic data tape (or floppy disk or hard disk...) and the pits and lands of a compact disc are essentially just bar codes imprinted in a different medium. 2. Base64 and bar codes have very different purposes. Base64 (and similar formats such as uuencode) are already a binary based encodings that are meant to be stored on electronic media. They are simply meant to make data binary safe for protocols that would otherwise require escaping for special characters. Meanwhile, the strength of bar codes is that they offer a machine readable form of data that is easy to attach to physical items that would otherwise offer no other electronic connectivity. Very different purposes.

There's no way one pack of gum was 67¢ in 1974.

And that no man might buy or sell, save he that had the mark, or the name of the beast, or the number of his name.

4:59. Yes. That is anatomically correct. ;)

Not sure if true.but a friend tdnme her grampa help invent the bar code. Maybe as in the machine or something. I was to young to ask her to clarify at the time.

I just learned yesterday that USAmerican craft chain Hobby Lobby doesn't use barcodes. It is because they are afraid that barcodds might "the mark of the beast". 😆 Instead they use a row of numbers.... which is just like a barcode, just without the barcode.

The video is interesting. The added background noise ("music") is 70% too lound and generally bloody annoying and distracting. What's the purpose of it? Thumb down. If I want to hear music, I use spotify.

I thought there were some fundamentalists who argued that these things were the so-called “Mark of the Beast.” That thought probably only lasted a little while, but I clearly remember some preachers huffing and puffing about these things signifying the end times.

So without bar codes we wouldn't have supermarkets being nearly as popular which means in the UK Milkmen would still exist with their electric van things. Damn Bar codes are really kinda a bad invention because they saved us time allowing for small shops to become less important & big shops to become more vital leading to the corporatisation of everything.

Agreed, horrible narration. The speaker has terrible diction and annunciation.

[@ssokolow]

"Usually hold 12 digits" ...how American of you. For example, they don't use UPCs in Europe... they use EANs, which are 13 digits, not 12. Do you know why ISBNs went to 13 digits when 10 ceased to be enough? Because they'd already become a subset of the EAN system assigned to a fictional country named Bookland so that European stores didn't need to have two separate barcodes for bookstores vs. supermarket displays.

1:57 "square barcodes"? A QR code is not a bar code. There are no bars.
